Vhm-314 Change Name Jun 2026

for connecting a serial adapter to your version of the VHM-314?

: Unlike more expensive modules like the HC-05 or CSR86xx series, the VHM-314 does not typically support standard AT commands (like AT+NAME ) via a simple serial interface.

One of the most frustrating aspects of the VHM‑314 is that even its default name is inconsistent. Different vendors, different batches, and different firmware versions cause the module to broadcast a variety of names. Here is a sample of what users have reported: Vhm-314 Change Name

If your project includes a microcontroller—such as an Arduino, ESP32, or Raspberry Pi—you can implement an electronic mask that rebrands how your master device interacts with the VHM-314, or use a micro-controller to intercept the pairing flow. Bluetooth Alias Mapping

Stick to basic alphanumeric characters (A–Z, 0–9) and avoid symbols or spaces when naming your device via AT commands or firmware files. Special characters can cause parsing errors in the underlying Bluetooth stack code, resulting in boot loops or a complete failure to advertise the Bluetooth beacon. for connecting a serial adapter to your version

Method 1: Editing the External Flash/EEPROM (Hardware Method)

Disconnect the programmer, power up the VHM-314, and scan for Bluetooth devices on your phone to verify the new name. Special characters can cause parsing errors in the

Within the software UI, navigate to the "Bluetooth Settings" or "Local Name" field. Replace the default text string "VHM-314" with your desired custom name (e.g., "Living Room Audio" ). Ensure the string length matches the maximum byte constraints allowed by the firmware (typically under 20 characters to prevent buffer issues).

The VHM-314 is a highly popular, low-cost Bluetooth audio receiver module used extensively by DIY electronics hobbyists. Out of the box, the board broadcasts a generic Service Set Identifier (SSID) or Bluetooth name, typically . While this default name works perfectly for isolated testing, it becomes problematic if you deploy multiple modules in your home or build custom Bluetooth speakers for friends and clients.
